NAME

       packetsender - Network utility for sending and receiving TCP, UDP, SSL packets

SYNOPSIS

       packetsender [options] address port data

DESCRIPTION

       Packet  Sender is a utility that sends and receives TCP, UDP and SSL (encrypted TCP) packets on the ports
       of your choosing. It supports IPv4 and IPv6 and provides a GUI for final users. However, is also possible
       use Packet Sender in text mode via command line.

       Some features:

              •  Can act as client/server to send and receive network traffic.

              •  A payload can be created in ASCII or hex.

              •  Command line mode is available for automation and scripting.

              •  Packet Sender cloud is a disposable resource to be used  to  publicly  display  and  distribute
                 packets  (via  an  URL)  for collaboration, tutorials, end users, etc. Packet Sender may import
                 public packet sets with public URL.

       Some uses:

              •  Control network-based devices in ways beyond their original apps.

              •  Test automation (using command line tool and/or hotkeys).

              •  Test network APIs (using the built-in TCP, UDP, SSL clients).

              •  Malware analysis (using the built-in UDP, TCP, SSL servers).

              •  Troubleshoot secure connections (using SSL).

              •  Test network connectivity/firewalls (by having 2 Packet Senders talk to each other).

              •  Stress-test a device (using intense network generator tool).

              •  Tech support (by sending customers a portable  Packet  Sender  with  pre-defined  settings  and
                 packets).

              •  Share/Save/Collaborate using the Packet Sender Cloud service.

OPTIONS

       -h, --help
              Displays help on commandline options.

       --help-all
              Displays help including Qt specific options.

       -v, --version
              Displays version information.

       -q, --quiet
              Quiet mode. Only output received data.

       -x, --hex
              Parse data-to-send as hex (default).

       -a, --ascii
              Parse data-to-send as mixed-ascii (like the GUI).

       -A, --ASCII
              Parse data-to-send as pure ascii (no \xx translation).

       -w, --wait <ms>
              Wait  up  to <milliseconds> for a response after sending.  Zero means do not wait (Default). It is
              compulsory if a reply from a server, as an HTTP server, is needed. In this case, -w 500 is a  good
              start value.

       -f, --file <path>
              Send contents of specified path. Max 10 MiB for UDP, 100 MiB for TCP/SSL.

       -b, --bind <port>
              Bind port. Default is 0 (dynamic).

       -6, --ipv6
              Force IPv6. Same as -B "::". Default is IP:Any.

       -4, --ipv4
              Force IPv4.  Same as -B "0.0.0.0". Default is IP:Any.

       -B, --bindip <IP>
              Bind custom IP. Default is IP:Any.

       -t, --tcp
              Send TCP (default).

       -s, --ssl
              Send SSL and ignore errors.

       -S, --SSL
              Send SSL and stop for errors.

       -u, --udp
              Send UDP.

       --http Send HTTP.

       -n, --name <name>
              Send previously saved packet named <name>. Other options overrides saved packet parameters.

       --bps <bps>
              Intense traffic. Calculate rate based on value of bits per second.

       --num <number>
              Intense traffic. Number of packets to send. Default unlimited.

       --rate <Hertz>
              Intense traffic. Rate. Ignored in bps option.

       --usdelay <microseconds>
              Intense traffic. Resend delay. Used if rate is 0.  Ignored in bps option.

       Arguments:

       address
              Destination address. Optional for saved packet.

       port   Destination port. Optional for saved packet.

       data   Data to send. Optional for saved packet.

EXAMPLES

       The  following  command  line will send a TCP packet, with a mixed-ascii as payload, to example.com, port
       22. The command will wait 500 ms for a reply.

           $ packetsender -taw 500 example.com 22 "Hello\nWorld"

       Similar to last command, but the TCP packet will be sent to port 21. An anonymous authentication will  be
       used.

           $ packetsender -taw 500 example.com 21 "USER anonymous\r\nPASS chrome@example.com\r\n"

       The command below uses SSL and will ignore SSL errors. The command will wait 500 ms for a reply.

           $ packetsender -saw 500 expired.packetsender.com 443 "GET / HTTP/1.0\r\n\r\n"

       Other good example how to access a homepage:

           $ packetsender -w 500 -a example.com 80 "GET / HTTP/1.1\r\nHost: example.com\r\n\r\n"

       Packet  Sender command line also can bind to custom ports to force IPv4/6 modes or multiple NIC, as shown
       below:

           $ packetsender -taw 3000 fe80::c07b:d517:e339:5a08 5005 "Hello\r"
           $ packetsender -taw 3000 192.168.0.201 5005 "Hello\r"
           $ packetsender -B 192.168.0.200 -taw 3000 192.168.0.201 5005 "Hello\r"
           $ packetsender -B fe80::a437:399a:3091:266a%ethernet_32769 -taw 3000 fe80::c07b:d517:e339:5a08 5005 "Hello\r"
           $ packetsender -B fe80::a437:399a:3091:266a -taw 3000 fe80::c07b:d517:e339:5a08 5005 "Hello\r"
